In the first part of this series, it was determined that the as-cast U-10Mo had a dendritic microstructure with chemical inhomogeneity and underwent eutectoid transformation during hot compression testing. In the present (second) part of the work, the as-cast samples were heat treated at several temperatures and times to homogenize the Mo content. Like the previous as-cast material, the homogenized materials were then tested under compression between 500 and 800 degrees C. The as-cast samples and those treated at 800 degrees C for 24 h had grain sizes of 25-30 mu m, whereas those treated at 1000 degrees C for 16 h had grain sizes around 250 mu m before testing. Upon compression testing, it was determined that the heat treatment had effects on the mechanical properties and the precipitation of the lamellar phase at subeutectoid temperatures.
